A crepe being cooked. Starch gelatinization is a process of breaking down of intermolecular bonds of starch molecules in the presence of water and heat, allowing the hydrogen bonding sites (the hydroxyl hydrogen and oxygen) to engage more water.
Retrogradation is a reaction that takes place when the amylose and amylopectin chains in cooked, gelatinized starch realign themselves as the cooked starch cools. [1]When native starch is heated and dissolved in water, the crystalline structure of amylose and amylopectin molecules is lost and they hydrate to form a viscous solution.
Liquid crystal (LC) is a state of matter whose properties are between those of conventional liquids and those of solid crystals.For example, a liquid crystal can flow like a liquid, but its molecules may be oriented in a common direction as in a solid.
Caramelization is a process of browning of sugar used extensively in cooking for the resulting butter-like flavor and brown color. The brown colors are produced by three groups of polymers: caramelans (C 24 H 36 O 18), caramelens (C 36 H 50 O 25), and caramelins (C 125 H 188 O 80).
Phase transitions (phase changes) that help describe polymorphism include polymorphic transitions as well as melting and vaporization transitions. According to IUPAC, a polymorphic transition is "A reversible transition of a solid crystalline phase at a certain temperature and pressure (the inversion point) to another phase of the same chemical composition with a different crystal structure."
Texture (cosmology), a theoretical topological defect in the structure of spacetime; Crystallographic texture, distribution of crystallographic orientations in a polycrystalline material; Texture (geology), a physical appearance or character of a rock; Texture mapping, a bitmap image applied to a surface in computer graphics
Quizlet was founded in 2005 by Andrew Sutherland as a studying tool to aid in memorization for his French class, which he claimed to have "aced". [6] [7] [8] ...
On 4 December 2006, 13:12 (UTC), a bot named Peelbot (contribs) added this article to the above physics articles category, whereas I believe that is a chemistry article, more precisely that of physical chemistry, since texture as a physicochemical property (crystallinity or amorphousness) is studied in solid state and also in materials ...
